Michael Nahm, in his Bigelow award-winning essay, "Climbing Mount Evidence: A Strategic Assessment of the Best Available
Evidence for the Survival of Human Consciousness after Permanent Bodily
Death," writes: "The
question of whether human consciousness can survive permanent bodily death is
one of the most tantalizing enigmas of our existence. Unfortunately, most
scientists shy away from addressing this enigma. Many seem to think that there
is not much to investigate because it has already been shown that consciousness
is produced by brain chemistry and will dissolve as soon as neuronal activity
ceases. However, I am convinced that this notion is inappropriate for two
reasons.
"First,
from a theoretical perspective, nothing in physics and chemistry predicts that
protons, electrons, atoms, or molecules will produce something like
consciousness. Therefore, trying to explain consciousness in physicochemical
terms amounts to backward reasoning from the start. In fact, William James, the
founder of American psychology, argued more than 100 years ago that it is
principally impossible to prove that brain chemistry produces consciousness—all
we can observe are 'concomitant variations' of brain states and states of
consciousness. Accordingly, many modern neuroscientists speak of 'neuronal
correlates' to states of consciousness in order to avoid fostering the
unwarranted notion that consciousness is produced by neuronal activity. Indeed,
there is not even a strict parallelism between brain states and states of
consciousness.
"Second,
from a practical perspective, many scientists have already investigated
phenomena at the frontiers of knowledge that question the physicochemical
“production hypothesis” of consciousness. These phenomena have chiefly been
studied in research disciplines known as psychical research or parapsychology. The
phenomena themselves are usually referred to as telepathy (conveying knowledge
or feelings from one individual to another without using the usual sensory
channels), clairvoyance (perceiving information or events without using the usual
sensory channels), precognition and retrocognition (perceiving future or past
events), and psychokinesis (psychically affecting matter). These psi phenomena occur
comparably rarely, but they do occur and they are perfectly natural. Millions
of people have experienced them in everyday life.
"Likewise,
phenomena suggestive of survival have been reported since time immemorial.
Hence, these experiences can be studied using standard methods of science. More
than that: Given that survival is one of the most fundamental questions facing
mankind, it is the duty of scientists to study survival-related phenomena, and
to do so with an impartial spirit. Among those who have often insisted that
studying such psi phenomena including survival should constitute the most
important function of science was the renowned biologist, philosopher and
parapsychologist Hans Driesch (1867–1941). He furthermore advocated for:
the
joy in tracing specifically those prospects the facticity of which has hardly
yet been explored, perhaps only foreboded. Only new discoveries take us
further, and the ‘newer’ they are, the more do they take us further. Hence my
interest in parapsychology.
"In
many of his writings, Driesch emphasized that, in natural science, empirical
data and arguments are of foremost significance. He stressed that when we
discover evidence for phenomena that don’t fit into the currently prevailing
world model, we must stay open to revising this model rather than disregarding
inconvenient data. Driesch proposed three guiding principles for the study of
psi phenomena that are as topical today as they were almost 100 years ago:
- Do not regard any fact “impossible”
in an aprioristic way.
- Do not believe that new facts must
necessarily be explained by means of explanations already established.
- Try to construct bridges to
established scientific disciplines.
"However,
it seems that only a few scientists shared such a rationale. One of them was
psychiatrist Ian Stevenson at the University of Virginia in Charlottesville,
who considered the study of spontaneous psychical phenomena occurring in
everyday life exceptionally important. He counted survival phenomena among
these. In a Presidential Address at a convention of the Parapsychological
Association in 1968, Stevenson presented three arguments for his desire to
develop improved methods for the study of spontaneous cases in parapsychology
in addition to performing quantitative laboratory experiments:
- Spontaneous cases provide some of
the best evidence we have for psi phenomena.
- They often provide much richer
information than the outcomes of laboratory experiments.
- They pertain to everyday life and
have a profound influence on the beliefs and actions of the people who
come into contact with them.
"Stevenson
was convinced that the withdrawal of many parapsychologists from the study of
spontaneous cases had resulted in a loss of public support and interest in
parapsychology. Although he admitted that studying such cases could have
methodological weaknesses, he insisted that the appropriate answer would
involve improving investigation methods rather than abandoning their study.
"I fully agree with
Stevenson’s appraisal, while adding that the possibilities for studying and
documenting spontaneous cases, including survival phenomena, have improved
considerably since 1968. Of course, they will continue to improve. Therefore,
the aims of the present BICS contest to identify the best available evidence
for human survival, to raise awareness among the public and within the
scientific community, and to encourage future research, are of supreme
topicality.
"In my contribution, I argue
that there is substantial evidence that establishes the survival of human
consciousness. By 'survival of human consciousness' or 'human survival, I mean
a broad notion covering 'any aspect of a personality that displays a seemingly
self-aware identification and verifiable knowledge continuity with a deceased
personality'.
"My essay is structured as
follows: In the succeeding Chapter 2, I identify the best available evidence
for survival among the different kinds of survival phenomena. I demonstrate
that this best evidence is constituted by cases of the reincarnation type
(CORT). While doing so, I largely treat the discussed survival phenomena as
reported and touch only lightly on their reliability and authenticity, or on
how they might best be explained. In order to be truly convincing, the power of
explanatory models for a range of given phenomena must be tested by applying
them to the most compelling data or evidence. Hence, the best survival evidence
among all considered phenomena should first be identified, and only then must
the nature of this best evidence be questioned in more depth. Therefore, I only
perform an in-depth discussion of different explanatory models for survival
phenomena with regard to CORT.
"But before that, Chapter 3
introduces several facets of CORT in more detail. Providing a more
comprehensive picture of the phenomenology of CORT is important for determining
the most appropriate explanatory model for them. This determination is crucial
because it is not enough to merely identify the best available evidence for
survival—one must also check whether this evidence is good evidence. As
philosopher Michael Sudduth pointed out, the best available evidence for
something can still be weak overall and lack persuasive power.
"The in-depth analysis of the
strength of the evidence for survival provided by CORT is performed in Chapter
4, relating it to two alternative explanatory models:
1. The physicalist model.
This model is based on the assumption that consciousness can be explained by
physics and its derivate, chemistry; it is the above-mentioned physicochemical 'production hypothesis' of consciousness. Here, psi phenomena such as telepathy
and clairvoyance cannot occur. Likewise, the extra-corporeal existence of
consciousness and memory, including survival, cannot occur. All witness
testimonies in CORT that favor survival are therefore regarded as flawed in one
way or another.
2. The living-agent psi model.
This model is based on the assumptions that eyewitness testimonies about
survival phenomena are largely authentic and that psi phenomena such as
telepathy and clairvoyance can occur. However, it is argued that survival
phenomena are not generated by the deceased, but by those still alive. Driven
by specific individual motives, living people activate hidden psi faculties and
psychically obtain the information required to simulate survival phenomena
including CORT. Thereby, usually without even consciously knowing it, they
fulfill their own hopes and needs—for example, by creating an apparition or, in
CORT, a 'reincarnated' loved one. This model might sound unreasonable for those
not familiar with parapsychology, but many parapsychologists acquainted with
the huge variety of psi phenomena take it very seriously and it is prominently
discussed in the literature concerning the survival question.
In Chapter 5, I put the
outcome of the discussions about CORT back into the larger perspective of other
survival phenomena and human life, and frame it in the context of 'proof beyond
a reasonable doubt' as requested in this contest.
In Chapter 6, I provide an
outlook concerning future perspectives.
